The use of "cmake -E touch_nocreate" added in commit v3.2.1~4^2 (Makefile: Fix multiple custom command outputs regression, 2015-03-06) caused builds to fail when one of the outputs is intentionally not created. This was fixed by our parent commit by making touch_nocreate succeed when the file is missing. Add a test case covering it. For the Watcom WMake generator, check for the SYMBOLIC source file property separately on each output. The mark is needed on outputs that are not really created to tell 'wmake' not to complain that it is missing. The mark is also needed on outputs that are created or 'wmake' will not consider them out of date when they exist. Inspired-by: Ben Boeckel <ben.boeckel@kitware.com>
